Fancy Color Diamond Necklaces

Yellow diamonds are graded by GIA/CGL from Fancy Light Yellow through Fancy Yellow, Fancy Intense Yellow, and Fancy Vivid Yellow. For a pendant worn daily, Fancy Light to Fancy Yellow offers a refined, wearable warmth. For a statement piece, Fancy Intense and Fancy Vivid — Canary Yellow — deliver a bold, vibrant color that stands out at the neckline. The more saturated the grade, the rarer and more expensive the stone. Because color can look different on screen versus in person, we recommend viewing stones at our office before purchasing.

Yes. Our fancy color diamond necklaces usually come with GIA or CGL certificates, which independently verify the color grade, clarity, carat weight, and confirmation that the color is natural and untreated. For color diamonds, certification is especially important — it establishes the authenticity of the color and underpins the stone's long-term value. Certificate details are listed on each product page.

Both make exceptional pendants but serve different purposes. Yellow diamonds are more widely available across a range of grades and budgets, with a warm, approachable beauty that suits everyday wear. Pink diamonds are significantly rarer — especially since the 2020 Argyle mine closure — and carry a sense of occasion and exclusivity that makes them ideal for milestone gifts and investment purchases. The right choice depends on budget, occasion, and the wearer's personal aesthetic.

Yes, often significantly. Fancy color diamonds are particularly sensitive to lighting conditions — the same stone can appear more or less saturated depending on whether it is viewed under LED, natural daylight, or incandescent light. Online photos are typically taken under controlled studio lighting and may not fully represent how a stone looks in everyday wear. We strongly recommend viewing color diamond pendants in person at our Okachimachi office before purchasing.

Yes. Our appointment-only office is in Okachimachi, Tokyo. For color diamond purchases in particular, an in-person visit makes a meaningful difference — you can see how the stone's color responds to different lighting and compare multiple grades side by side. Please book an appointment through our contact page or by phone.

Yes. We can create a custom pendant using your preferred color diamond — yellow, pink, or green — in the grade, carat weight, shape, and metal of your choice. You can also browse our loose color diamond collection to select a specific stone and we will design the pendant around it. Contact us to discuss your requirements.

Natural fancy color diamonds — particularly pink, green, and blue — are among the most sought-after stones for investment due to their extreme rarity. Yellow diamonds in Fancy Intense and Fancy Vivid grades also command strong market interest. As with any investment asset, value depends on grade, certification, and market conditions. Choosing a GIA or CGL certified natural diamond is the essential foundation for any purchase intended to hold long-term value.
